Next-generation React databases

About

How do you manage user data in your React Native app? A popular approach is to use Redux or MobX with a persistence adapter. This works great for small, simple apps, but it has a serious flaw: it doesn't scale very well. Introducing WatermelonDB — a next generation database for React and React Native. Here's why you should care: - Highly scalable. Works as well for 20,000 database records as it does for 100. Instant launch. No matter how much data you have, the app still launches with near-zero performance penalty - Lazy loaded everything. Don't load all data at launch, query only the exact records you need. That's why it's fast! - Fully reactive. All records and queries are observable using RxJS. A change in one place propagates to all other places automatically - Made for React. Comes with a HOC so you can declaratively tie together data and components - Relational. Document stores are simple, but relational databases are powerful. Want to find, say, all posts that have a comment by user X? Sure, that'll be about a millisecond. - Cross-platform. Works on iOS and Android (using SQLite), on the web (using LokiJS), and it's easy to add more - Performant. Uses asynchronous processing, multi-threading (also on the web), resource sharing, and caching to squeeze extra performance - Built for sync. Comes with syncing primitives so you can supply your own synchronization code
